Problems solved by technology

Most of the nitrogen absorbed by peanuts comes from the nitrogen fixation of rhizobia, accounting for about 70%. Increasing the application of phosphorus fertilizer can promote the symbiotic nitrogen fixation of rhizobia, and potassium fertilizer can also promote the growth and development of peanuts and the symbiotic nitrogen fixation of rhizobia. Potassium fertilizer has no obvious effect on increasing production, but it has obvious effect when used in combination with phosphorus fertilizer

Embodiment 1

[0046] Raw material ratio: 360 parts of urea, 145 parts of monoammonium phosphate, and 300 parts of potassium sulfate.

[0047] The specific production process is as follows:

[0048] 1. Measure urea, monoammonium phosphate, and potassium sulfate according to the ratio and then fully stir and mix them in the stirring pot;

[0049] 2. After the above materials are mixed evenly, they are conveyed into the granulator by a belt. A nozzle is installed in front of the granulator to spray steam to make the materials into balls and granulate. The granulation temperature is controlled at 40°C-50°C;

[0050] 3. The preliminary pelletized material enters the first drying drum and the first cooling drum in turn, and the temperature of the first drying outlet is controlled at 60°C-70°C;

[0051] 4. After the first cooling drum is discharged, the material is screened, and the large particles screened out are crushed and put into the granulator for granulation; the semi-finished products ob...

Embodiment 2

[0055] Raw material ratio: 365 parts of urea, 120 parts of monoammonium phosphate, 65 parts of calcium magnesium phosphate fertilizer, 300 parts of potassium sulfate, 15 parts of borax, 8 parts of EDTA chelated iron, 6 parts of EDTA chelated manganese, 7 parts of EDTA chelated zinc, 1 part of ammonium heptamolybdate.

[0056] Concrete production technology is with embodiment 1.

[0057] The obtained product has the specifications of 18-7-15, contains medium and trace elements, and does not contain seaweed extract and seaweed residue.

Embodiment 3

[0059] Raw material ratio: 365 parts of urea, 120 parts of monoammonium phosphate, 65 parts of calcium magnesium phosphate fertilizer, 300 parts of potassium sulfate, 15 parts of borax, 8 parts of EDTA chelated iron, 6 parts of EDTA chelated manganese, 7 parts of EDTA chelated zinc, 1 part of ammonium heptamolybdate, 10 parts of seaweed extract (note: 50 parts of liquid, namely 10 parts of dry basis).

[0060] Concrete production process is the same as embodiment 1 except step 2.

[0061] Step 2: After the above materials are mixed evenly, they are conveyed into the granulator by a belt. Two nozzles are installed at the front of the granulator, one of which sprays a certain amount of seaweed extract calculated according to the proportion, and the other nozzle sprays steam to make the material into a granulator. Ball granulation, the granulation temperature is controlled at 40°C-50°C.

[0062] The obtained product has the specification of 18-7-15, contains medium and trace ele...

Abstract

The invention discloses a method for preparing a special alga fertilizer for peanuts, belonging to the technical field of production of special fertilizers for crops. The fertilizer is prepared from urea, monoammonium phosphate, a calcium magnesia phosphate fertilizer, potassium sulfate, sodium borate, EDTA chelated iron, EDTA chelated manganese, EDTA chelated zinc, ammonium heptamolybdate, an alga extracting solution and alga residues. Compared with the prior art, the special high-activity alga for peanuts has the advantages of reasonable proportioning and comprehensive nutrients, and can increase the peanut yield and enhance the peanut quality.

Description

[0001] This application is a divisional application filed by the applicant Stanley Chemical Fertilizer Co., Ltd. "The name of the invention is: a special seaweed fertilizer for peanuts and its preparation method, the application date is August 27, 2014, and the application number is: 2014104267280". technical field [0002] The invention belongs to the technical field of crop special fertilizer production, in particular to a method for preparing seaweed fertilizer special for peanuts. Background technique [0003] Peanut was introduced to my country in the 16th century and is one of the four major oil crops in my country. Among the crops in China, peanut planting area and total output value rank seventh and fifth respectively. my country's peanut planting area is second only to rapeseed, with a planting area of ​​about 5 million hectares and a total output of about 14 million tons, accounting for more than 40% of the world's total peanut production, ranking first in the world...
